  • Patent number: 3967179
    Abstract: A stepping motor is energized by a power supply that supplies charges of power with the number and duration of the charges being controlled according to the current operating conditions of the motor. The charges are supplied to a capacitor across which the motor is connected for energization with the voltage developed across the capacitor being the voltage supplied the motor.

  • Patent number: 3963971
    Abstract: A digital circuit for translating each input command pulse into an incremental step of a digital motor in which the input pulses may be received at any rate while the pulses to the motor and hence the motor velocity are produced at rates which is within the motor's ability to change its velocity. The system uses a digitally operated circuit that can be easily adjusted to different motor velocity abilities and also enables control over both directions of motor movement.

  • Patent number: 3955739
    Abstract: A hydraulically actuated power cylinder reciprocates a driver to exert a compressive force to upset a rivet with the power cylinder's movement being made to correspond to the movement of a pump cylinder by a fluid connection therebetween. The pump cylinder's movements are mechanically actuated according to a programmed cam and actuation is made to occur only during the riveting cycle by a control circuit operating a clutch and brake with the circuit inhibiting operation upon the sensing of a malfunction.

  • Patent number: 3949285
    Abstract: A lathe numerical control system for cutting a tapered thread by a cutting tool that is moved along a rotating workpiece in steps on both a lead axis and a radius axis. Synchronism of movement along both axes with the workpiece rotation is achieved by an encoder producing a set number of pulses per revolution of the workpiece and these pulses are directed simultaneously to a lead axis path and a radius axis path with each path effectively dividing its encoder pulses to produce the steps needed for the tool movement to produce a thread for each revolution.

  • Patent number: 3942724
    Abstract: A nozzle having a through passageway in which the flow of pressurized fluid induces the flow of secondary fluid therethrough with the passageway having a throat that is adjustable in cross-sectional extent to enable the nozzle to efficiently operate over a wide range of operating conditions. The throat extent may be automatically changed with a change in the operating condition within its range or as in one embodiment be easily set for one operating condition.

  • Patent number: 3933017
    Abstract: A key holder consisting of a flat sheet and a bifurcated fastener that holds one or more keys to the sheet by its bendable legs passing through a rectangular slot to thereby prevent rotation of the fastener while permitting relative rotation of the key. A rack holds a plurality of key carrying holders in at least one row with the holders being inclined to enable identifying indicia to be visible and to facilitate removal and replacement of the holder in the rack.
